A defense lawyer for a murder suspect says prosecutors in Arkansas and Oklahoma are trying to keep her from presenting evidence that could aid her client.

Twenty-five-year-old Elvis Thacker and his 24-year-old brother Johnathen are accused of sexually assaulting and killing 22-year-old Briana Jane Ault of Fort Smith, Ark. Her body was found in an Oklahoma pond three years ago.

Oklahoma prosecutors Monday asked a judge to quash subpoenas seeking testimony from Arkansas officials. The Southwest Times Record newspaper reported (http://bit.ly/1a5hgZt ) that defense lawyer Gretchen Mosley said an Arkansas prosecutor was interfering with witnesses, but the judge cut her off after an Oklahoma prosecutor objected.

The judge wouldn't set aside the subpoenas but asked lawyers to work things out because the officials are listed as witnesses for both sides.
